OIL BURNER.

Application filed April 3,

To all whom it may concern:

Be it known that 1, JOHN V7. LABIMORE, citizen of the United States, residing at Mountain Grove, in the county of Wright and State of Missouri, have invented certain new and useful Improvements in Oil Burners, of which the following is a peciflcation.

This invention relates to gas generating oil burners of the type particularly designed for heating purposes and adapted to use low grade fuel oils such as kerosene.

It is well known that the efficiency of burners of this type often becomes impaired by the accumulation of carbon deposits or soot, but otherwise these burners are superior in many respects to other forms of heating apparatus, especially in regions where low grade fuel oils are readily available for use. Therefore, by providing a practical and convenient means for eliminating or reducing the carbon deposit the proper functioning and reliable operation of a burner of this type is always assured.

Accordingly, the present invent-ion has particularly in view a novel burner device which also generates a suflicient quantity of steam along with the gas vapor, whereby during the process of combustion at the burner, the oxygen of the steam will destroy the carbon which would otherwise be deposited in the form of soot.

A further object of the invention is to provide a novel burner device and novel means for supplying the fuel oil and water in the proper proportions, whereby the latter although being fed to the burner along with the fueloil, will not interfere with the operation of the burner.

WVith the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which:

Figure 2 is an enlarged detail sectional view of the valve device for controlling the su aply of fuel oil to the burner units.

corresponding parts throughout the several figures of the drawings.

In carrying the present invention into effect it is proposed to provide a burner device of the type w ierein the fuel oil is transformed into vapor which ignites to provide the heating flame, and as will be observed from Figure 1 of the drawings the present P3111131 device, designated in its entirety as b, is preferably adjustably supported upon asuitable stand S by means of a clamping plate 1 whereby the height of the burner may be regulated with reference to the element to be heated. This burner device may be placed within the fire box of a heating stove range or furnace to produce the desired heating effect, and after its operation 15 once started it continues as long as the required amount of fuel is supplied thereto.

Referring to the structural features and characteristics of the said burner device B it will be observed that the same consists of a pair of relatively separate and independentheating' units 1 and 2, either or both of which may be operated simultaneously acgprding to the required heating capacity. Eta-ch unit is a duplicate in construction and includes a vertical pipe section 3 which is adapted to be engaged by the clamping plate P of the supporting stand, while the upper end thereof is bent at right angles as indicatec at d, to provide a generating section and is then doubled downwardly and under the section t to produce the elbow 5 and burner section 6. The open extremity of the said section 6 is capped as at 7 and provided with the jet orifice 8 disposed directly beneath the generating section l.

the purpose of spreading or dispersing the flame to increase the heating efficiency hereof it is proposed to mount a suitable lame spreader 9 upon the generator section This flame spreader is preferably in the form of a plate having the opposite upstanding fianges 10 provided with openings or perforations whereby the spreader may be fitted over the burner section 6 of the pipe before the cap 7 is placed thereon, and then slid into final position as shown. The lower end of the vertical pipe 3 communicates with a substantially horizontal pine section 11 which is suitably connected with a fuel supply controlling valve designated generally as 12.

lhe said fuel supply controlling valve is shown in detail in Figure 2, and preferably includes a body portion 13 having a fuel receiving nipple 14 which may be connected with the fuel supply line 15 at one end while its opposite end communicates with the op positely disposed valve openings 16 and 16. These valve openings communicate with the enlarged fuel receiving chambers 17 and 17 of the valve body, and the latter in turn communicate with the discharge openings 18 and 18 in the discharge nipples 19 and 19 which respectively supply the separate units 1 and 2 with the necessary fuel and water as will presently appear. F or the purpose of controlling the valve passages 16 and 16 the separate needle valves 20 and 21 are employed, and as shown the stems thereof which operate within the chambers 17 and 17 are'of reduced diameter to maintain the capacity of the said chambers, while the conical ends thereof cooperate with the rims of the valve openings 16 and 16 to control the quantity of fuel issuing therefrom. With this arrangement it will be apparent that either of the burner units 1 and 2 may be 0perated independently ofthe other, and the amount of fuel supplied to the burners may also be properly regulated. 7

As previously indicated,-the fuel supply controlling valve 12 is connected with the main fuel supply pipe line 15, and this pipe line is not only intended to supply the fuel oil, but also at proper intervals, relatively small quantities of water. That is to say, the fuel supply line 15 has connected there with a fuel supply tank 22 which is arranged at a higher level than the heating units of the burner device, whereby suflicient pressure will be maintained in the fuel line to keep the burners supplied, through the medium of the controlling valve 12, and the said fuel line also has in communication therewith a water supply tank 23 preferably arranged at a higher level than the fuel tank 22. In order that the water may be fed through the burner along with the fuel in relatively small quantities at the proper intervals, the water supply tank 23 is provided at its discharge end with a suitable needle valve 2st which permits of adjusting the size of the. water discharge opening of the tank to permit water to issue into the fuel supply line 15 in a series of drops at regularly spaced periods.

\Vhen the burner is first started it is of course proposed to cut off all supply of water but after it has attained its full operation and the generator is sufficiently heated, the needle valve 24 is adjusted to permit the desired quantity of water to pass on through the fuel supply line with the fuelto be carried. into the generator whereby it will be immediately transformed into steam and escape through the jet orifice 8 of the burner to consume the carbon in the fuel flame. This not only causes a burner flame of intense heat but at the same time destroys the carbon of the flame which is ordinarily disposed as soot.

From the foregoing it will be apparent that the invention provides a burner device having combined fuel and water supply means for simultaneously generating gas and steam which latter effectively destroys the carbon of the subsequent flaineand maintains the efficiency of the burner. By reason of the water being fed along with the fuel in the porper proportions the elimination of the carbon automatically takes place, and involves no manual attention; Furthermore, this arrangement provides a simple and compact means for supplying the oxygen to the burner flame in the form of steam which is vaporized simultaneously with the fuel oil and forms a highly combustible gaseous miX- ture.

By reference to the manner of operation of the apparatus, it is to be noted that when it is desired to start the same it is necessary that the needle valve 2 1 of the water supply means he closed so that only fuel oil reaches the controlling valve 12. lVhen the needle valves 20 and 21 are open fuel oil will then flow into the horizontal pipe sections 11 and thence to the burner heads which include the generator pipe section l and the burner section 6. The flame spreader pans 9 which are suspended from the generator sections of the burner head may have placed thereon a suitable priming charge of fuel which when ignited will heat the generator section 4 to begin the necessary vaporization of the fuel and start the burner 6, and after the generating action is thoroughly in effect the needle valve 24: of the water supply means may be adjusted to let water int-o the supply line 15. By reason of the fact that pipe 15 is of relatively small diameter and the specific gravity of water is heavier than that of the oil, the water will have a piston-like effect in passing through the said supply tube or pipe 15 and insure the carrying of a proper amount of fuel to the fuel supply cont-rolling valve and also the burner head.

' Vvithout further description it is thought that the features and advantages of the present invention will be readily apparent, and it will of course be understood that changes in the form, proportion and minor details of construction, may be resorted to without departing from the spirit of the invention or the scope of the appended claim.
